Nice.
If you make an .exe or .bat file to start that vbs file automatically during each startup, then there will be more fun unless user deletes it.

Wait....
So u mean gravity is relative?
I had also heard about inertial frame of reference. But don't know wthat it is.

Ya there are only 5 numbers in base 5 system (quinary). So how can there be 8 in it?

Hi,
Mine favorites are physics, math and computer science. smile

I also like that one. up Euler's equation. Also the god equation but I dont know how to use it. roflol

#7 Re: Help Me ! » Complex Quadratic » 2025-03-05 22:10:03

What's your favorite equation?

#8 Re: Help Me ! » Complex Quadratic » 2025-03-05 00:34:48

Ok!
Other than plotting complex numbers, what are other uses of a complex plain?

#9 Re: Help Me ! » Complex Quadratic » 2025-03-04 01:11:13

I understood it. Is complex plain only used to plot complex numbers on the graph?

#10 Re: Help Me ! » Complex Quadratic » 2025-03-04 00:55:51

Thanks sir!
What should I call you?

#13 Re: Help Me ! » Complex Quadratic » 2025-03-03 01:55:06

This is very BF but I would really like to see that.

#15 Re: Help Me ! » Complex Quadratic » 2025-03-02 22:59:15

I first removed the complex number and then tried to find x. Can you please explain the De Moivre's theorem?

But mathematically it seems inmpossible to make the guests meet with all each other. Lets first check it mathematically. wink

I am hosting a progressive dinner with 28 guests. They need to rotate to 4 different homes for 4 different courses. I would like everyone to meet at least once.

So it means that each guest has to get a new course. So that isn't allowed.

The quadratic formula will still work here.

How will it work here? I tried it and I couldnt simplify it.

#19 Re: Help Me ! » Dinner puzzle....Please help! » 2025-02-27 23:00:57

Why do 1, 8, 15 and 22 take the same course 4 times?

#20 Re: Help Me ! » Complex Quadratic » 2025-02-27 15:59:32

x = 13/root(-101)
or let's say: x = 13root(101)i / 101

#21 Re: Help Me ! » Dinner puzzle....Please help! » 2025-02-27 14:22:57

I tried 5 different ways to complete this but all were useless. At first I tried to match all guests with each other so thought of first making G2 meet with all. I made him meet with 16 other guests but later didn't get anything useful so left the method.

#22 Re: Help Me ! » Dinner puzzle....Please help! » 2025-02-26 00:35:46

Interesting. I will surely try it.
Why don't we use sudoku and abit algebra to solve it? wink
I'll try doing in paper and if I don't get the answer, I'll try python or JS.

#23 Re: Help Me ! » Dinner puzzle....Please help! » 2025-02-25 20:36:07

Can you please explain what does this puzzle really mean?

#25 Re: Dark Discussions at Cafe Infinity » malware warning » 2025-02-25 20:25:47

Ya surely I will try to help you.
Do you use linux?
